You are requesting something like this

in the boot loader, use the kernel option
init=/pre-init.sh
where /pre-init.sh is executable by root and contains something like this:

#!/bin/sh
/bin/mount -n -t ext3 -o noatime /dev/hda2 /etc
## /etc/mtab and /proc/mounts to be checked later!
exec /sbin/init
## one might need "$@" or something at the end of the line to pass 
## default runlevel and boot loader parameters ?

But you should consider the more advanced methods used by live cd
(knoppix and many others)
